  • 9n Serial Number
  • Ok Guys, I need your help, I have a 9n tractor with what appears to be a serial number of 9n131494 it's very hard to read. Does anyone know what year that tractor would be. I need to replace the crankshaft, they are pricy, I'm trying figure out what yr my tractor is based off that number. Any information would be greatly appreciated.

  • HiYa Todd-
    FORD liked to keep things simple. According to the 39-53 MPC, the crankshaft, part number 9N-6303-A, was used from '39 - '52 so that answers that question. One way to verify that or any other part is to seek out the MPC's. The Master Parts Catalogs will list all the parts of the tractor and if one was modified, updated, or redesigned, it was noted by part prefix and/or suffixes. When the 9N was released in June, 1939, all new parts for it carried the '9N' prefix. Note if and when FORD used an existing part, the MPC would note it, such as 'B', '40', or '01A'. FORD nomenclature has every part by category -it is the part prefix that dictates which module (car, truck, tractor)it is used on. A '9N' prefix code means that was the first module the part was used on. For example, FORD generators are all listed as part number xxx-10000 with the prefix code defining which module it was used on. When the 8N Tractor was released in July, 1947, the new generator was revamped to the 3-Wire/3-Brush 11 AMP 'A' Circuit Design unit now using a Voltage Regulator instead of the roundcan cutout. It had the new part number 8N-10000 because it was a new design replacing the prior 2N-10000 1-Wire/3-Brush unit. So, why do you think you need anew crankshaft? New ones are no longer made for one thing. If rebuilding your engine, old one needs to be reground and then new bearings made to fit. Consult a qualified machine shop. Just some friendly advice.

  • Not that it matters for the crank shaft but that serial number is a 1944 2N.

  • Going to take a chance here, but I believe the cranks are all the same from 1939-50 models.
